How to Grow Spinach for High Yield? A Detailed Guide to Practical Growing Techniques
Spinach is a very common leafy vegetable on dinner tables in China, and it is grown over a very large area. With the growing market demand for spinach today, its yield also urgently needs to increase. Raising spinach yields can not only meet market demand but also help growers improve their growing returns. So how should spinach be grown to achieve high yields? Below, the editor will give you a brief introduction. Let's take a look!
1. Variety selection
If you want to increase spinach yields, variety selection is crucial. We must ensure the planted variety has good production capacity, strong disease resistance, and thick, dark leaves. Moreover, because spinach has high nutritional value and its growing returns are relatively obvious, variety selection is very important. After choosing the variety, before sowing we also need to carry out sprouting and disinfection of the seeds, soaking them in warm water and chemicals. This eliminates pathogens inside the seeds and increases the seed germination rate.
2. Land preparation and fertilization
If the previous crop in the soil was a fruit vegetable crop, then when planting spinach you can appropriately apply less organic fertilizer. Because the growth of fruit vegetables has a very large demand for organic fertilizer, you only need to broadcast some compound fertilizer. First, we need to deep plow the soil, then rake it level and loosen it once, and rake the bed surface flat. Then apply compound fertilizer, generally broadcasting about 450g per sq m. If the previous crop was a vegetable, then less fertilizer remains, so about 5000kg of farmyard manure still needs to be applied per mu, mixed with the soil, and beds made ready for sowing.
3. Timely sowing
We should regulate the sowing time according to the growing region. For example, if growing in the north, sowing should be done after National Day. Before sowing, pick out the shriveled seeds with low purity and many impurities to ensure uniform emergence and the growth capacity of the seedlings. Usually about 10g is sown per sq m. The main sowing method for spinach seeds is broadcasting, scattering the seeds evenly over the bed surface. Then rake the bed surface once more, keeping the depth at about 1.2 cm. Then press it down gently and water appropriately to promote seed germination.
4. Management after sowing
After sowing, the temperature difference between day and night is relatively large. When daytime temperatures are high, the greenhouse film should be appropriately opened to do a good job of ventilation and cooling. At night, the film should be put back to keep warm. About 5 days after sowing, spinach should emerge uniformly, so two days after sowing it should be watered appropriately to ensure uniform emergence. After emergence, the soil should also be kept moist to meet spinach's water needs. Finally, do a good job of weed control, using chemicals such as paraquat as appropriate, and be careful to control the concentration to avoid pesticide damage to the seedlings.
The above is a brief introduction to how to grow spinach for high yield. Spinach growing methods are relatively simple, but if you want high yields, then management is very important, so everyone must pay close attention. That is all for today's introduction.
